Well...not that easy at the moment. If you got a good texteditor which can use scripts or macros, you can modify the MAME datfile. You can add so called "rebuildto" tags and use the rebuilder afterwards to rebuild the files to a new place.

So the datfile looks something like:

game (
name puckman
sourcefile "pacman.c"
description "PuckMan (Japan set 1, Probably Bootleg)"
year 1980
manufacturer "Namco"
rebuildto "Namco"


not very comfortable or easy....
I will think about some additional rebuilder pre-folder. Something like rebuilderdestination "d:\temp\test\%m", where %m will be a variable with the sets' manufactur name.
In fact that should be rather easy to add.
